Anti-syphon safety dispenser

Abstract

A dispenser apparatus for delivering water to a chemical or agricultural tank wherein a base plate is provided to removably attach the dispenser to the tank. An upstanding screw-threaded pedestal member extends from the base plate and carries a valved dispensing line that may be pivoted with regard to the horizontal as well as adjusted vertically. The screw-threaded pedestal member also allows the dispensing line to be revolved to any desired horizontally disposed dispensing position.

What is claimed is: 
     
       1. An improved fluid dispenser comprising a base plate adapted to be connected to a fluid receiving tank having a feed opening, a pedestal member extending upwardly from said base plate, a collar member in surrounding relationship to said pedestal member and adjustably mounted with respect thereto, a carriage assembly including a fluid feed line attached to the upper end of said collar member, valve means in said feed line to control the flow of fluid therein, said collar member being vertically adjustable on and revolvably mounted with respect to the pedestal member by means of corresponding and mating screw threads on each of said collar member and said pedestal member, means for pivotally mounting said carriage assembly to the upper end of said collar member, said carriage assembly including a pair of bracket members attached thereto and in surrounding relationship to said feed line, said feed line including a hose connector means at one end thereof, said feed line further including a spigot having a check valve therein at the other end thereof, a pair of spaced locking nuts in surrounding relationship to said pedestal member and interposed between said base plate and said collar member, one of said pair of locking nuts being located adjacent said base plate and the other of said locking nuts being located adjacent said collar member to vertically adjust said collar member on said pedestal member, said base plate being channel-like in configuration and including a pair of flange members with each of said flange members having bar means in association therewith for extending into openings in said fluid receiving tank to mount said dispenser on said tank, and wherein said flange members are hinged to said base plate to accomodate different sized fluid receiving tanks. 
     
     
       2. The dispenser described in claim 1 wherein said check valve is a monodirectional valve means in said spigot for preventing backflow of aqueous mixture into the fluid in said feed line and allowing flow of fluid out of said spigot and into aqueous mixture in said tank. 
     
     
       3. The dispenser described in claim 2 wherein bracket means are secured to said carriage assembly to limit counterclockwise rotation of said carriage assembly whereby said spigot is prevented from entering said feed opening.
